ATTACHMENT FOR CARDING MACHINES.

Application filed January 16, 1926.

The invention is applicable to carding machines of the class having side delivery rolls at one end of the doffer, to which rolls the fleece or sliver stripped from the doifer by,

means of the usual vibrating doifer knife passes after going through a rotating condenser tube.

It is usual to provide such carding Inachines with means for supporting the fleece or sliver as it falls from the doifer, and during its travel transversely of the machine toward the condenser tube and side delivery rolls. The present invention comprises an improvement in such means. The gist of the invention consists in a fleece or sliver support composed of a series of frustro-conical roll-sections disposed end to end lengthwise of the doffer, with the small end of one such section at the large end of the next adjoining section, and so on throughout the series.

An illustrative embodiment of the invention is shown in the drawing applied at the front of a carding machine, the view being in perspective. I I

In the drawing the doifer is marked 1, the vibrating doifer knife being marked 2, the side-delivery roll mechanism being marked 3, and the rotating condenser tube being shown partly at 4. At 5 is indicated fleece or sliver which has been stripped from the doffer by the action of the dofiing knife. Such fleece or sliver is mostly concealed by the rockshaft of the doffer knife. It is indicated as, occupying the space or interval between the surface of therdofier and the surfaces of the frustro-conical roll-sections 6, 6. At the delivery side of the side-delivery rolls 3 the fleece or sliver is shown as extending upward from the delivery rolls 3 on its way to the overheadguide arrangesections.

site side-frames 7, 7, of the machine. The frustro-conical roll-sections are rotated in the same direction as the doffer by means of a belt 8 which passes around a pulley (not shown) in connection with the dolfer and also around a pulley 9 which is connected fixedly with shaft 61 and the series of roll- It is to be noted that the increase in diameter of the respective frustro-conical roll-sections is in the direction toward the condenser tube and delivery-roll arrangement. The peripheries of the large ends of the frustroronical roll-sections are fairly close to the periphery of the dofler.

The fleece or sliver, as it is stripped from the doffer by the doffer knife, falls down.

into the space between the frustro-conical roll-sections and the doffer and is supported by the said roll-sections. By the turning of the frustro-conica1 roll-sections over toward the doflfer-surface such portions of the fleece or sliver as may float frontward over the said roll-sections is carried rearward toward the doffer, so that all of the fleece or sliver becomes gathered together in consequence of the rotation of the condenser tube. The larger diameters of the frustro-conical rollsections support the fleece or sliver at intervals across the face of the dofler sufliciently close to one another to prevent the fleece or sliver from dropping through between the said roll-sections and the doifer. The conical shape of the respective sections assists in feeding the fleece or sliver transversely of the machine toward the condenser tube 4 and side-delivery arrangement 3, the feedingaction being repeated by each frustroconical roll-section in succession.

In the practical utilization of the prin ciples of the invention, the constructional features of the series of frustro-conical rollsections, their supporting means, and their driving means may bevaried to meet practicalrequirements andaccording to the views of the maker.

What is claimed as the invention is 1. In a carding machine, the combination with the doffer, means for stripping the fleece "therefrom, and side-delivery mecha nism, of a series of rotating fleece-supporting frustro-conical roll-sections disposed end to end lengthwise of the dofler, with the small end of one thereof at the large end of the next adjoining, and so on throughout the series.

2. In a carding machine, the combination with the dofier, means for stripping the 5 fleece therefrom, and side-delivery mechanism, of a series of fleece-supporting frustroconical roll-sections extending end to end lengthwise of the dofl'er, with the small end of one thereof at the large end of the next adjoining, and so on throughout the series, a 10 supporting shaft for said series, and means for rotating the series.
